   In the above case simulate does perfectly mean emulate   
   because HHH is anchored in a world class x86 emulator.   
      
   The problem with x86 emulation is essentially no one   
   has even a slight clue about the simple semantics of   
   the x86 language. Because of this I switched to simulate   
   as in a C interpreter emulates code written in C.   
      
   HHH has been a fully operational simulating termination   
   analyzer with a limited domain for three years.   
      
   It should not be an impossibly difficult issue for   
   an experienced C programmer to understand that when   
   one C function simulates another that this means   
   that the former is equivalent to a C interpreter   
   that is anchored in the semantics of the C programming   
   language.   
      
   No one needs to see the actual code of HHH to get   
   that gist. Above is the actual code.

   My 28 year goal has been to make   
   "true on the basis of meaning" computable.
